摘要: The binding behaviour of an acid dye, sodium 1-phenylazo-2-hydroxy-6-naphthalenesulphonate, with bolaform electrolytes containing a benzene ring as spacer group in aqueous solutions was investigated by means visible absorption spectroscopy. spectral change the dye strongly dependent on structure terminal groups. electrolytes, having various N,N-dimethyl-N-alkylammonium pyridinium groups, formed 1:1 complexes dye. constant electrolyte-containing 4-(N,N-dimethylamino)pyridinium largest because its structure. thermodynamic parameters for were also affected length alkyl chains properties. Electrolytes 10 carbon atoms supramolecular (two dyes to one electrolyte). It is concluded that connected and electrolytes.
